The Spider of Leng is slow, but brutal and relentless. Its bite is quite damaging, and it can stun lock you in the tight tunnels left by the Chthonian.

There is no known way to kill the giant spider; it is completely invulnerable to all attacks and does not recoil or even react to assaults from the most damaging weapons. However, the player can lure it to the pit it came from, causing it to fall and disappear. This difficult-but-satisfying victory is accomplished by quickly-and-carefully running to lead the Spider of Leng away from its hole and then dashing back past it and not stopping until Emily/Edward is on the far side of the hole. The Spider will simply keep creeping toward the protagonist and fall into the hole between them!
